Designed for 2015-2021 Mercedes Sprinter 3500 4WD vans, the factory front suspension relies on a MacPherson strut for damping, which can quickly become overwhelmed once the van is upfitted for overlanding or used to haul heavy cargo. Fabtech addresses this limitation by pairing a Bilstein strut with their high-quality cold-wound coil springs to significantly improve ride quality and suspension control.
The coil springs are positioned around the strut bodies and provide an additional 1"-1.5" of lift over stock. This added ride height increases ground clearance and allows for fitment of larger tires for off-road use, while also helping to reduce body sway on vans with full interior build-outs or heavy cargo loads.
Fabtech’s coil springs utilize billet aluminum upper and lower coil seats that slide over the strut bodies, ensuring proper spring positioning and a secure mounting point at the correct ride height.
To further enhance suspension performance, Fabtech developed an auxiliary front shock kit that adds two Dirt Logic 2.25 shocks with Sprinter-specific valving. This custom valving delivers excellent ride quality whether the van is fully loaded or unloaded. The Dirt Logic 2.25 shocks feature stainless steel bodies for maximum corrosion resistance in all environments.
The heavy-duty auxiliary shock mounts are constructed from 1/4" thick steel and attach directly to the suspension subframe, eliminating any attachment to the unibody. This subframe-mounted design helps isolate road noise and prevents unnecessary stress to the vehicle’s body structure. Installation requires drilling only two holes, takes approximately 1-2 hours, and does not require any interior removal.
This coil assist and auxiliary shock system is the ideal upgrade for Sprinter owners seeking improved suspension damping, enhanced stability, and confident performance on highways and off-road trails.
